Tina: For centuries oceans and human eccentricity have been linked in the literary and artistic imagination.
Tina's Claims
1. For centuries oceans and human eccentricity have been linked in the literary / artistic imagination.
2. The link between oceans and human eccentricity probably came from when Europeans used ships as asylums for unwatned weirdos during the Renaissance.
Sergio's Responses
1. AGREES + DISAGREES. Sergio would definitely agree that oceans and human eccentricity have been linked for centuries, but he'd disagree that it's only been for centuries. He's saying that oceans have always been linked to eccentricity.
2. DISAGREES. Sergio wouldn't agree that the link between oceans and human eccentricity began with the Renaissance practice of putting weirdos out to sea. He thinks that oceans and eccentricity have always been linked. It didn't start in the Renaissance.
Goal
Since Sergio seems to be disagreeing with Tina's explicit ideas, we have enough of a prephrase to head to the answers.
We're arguing over whether oceans / eccentricity have been linked since the Renaissance (because they put weirdos out to sea), or whether oceans / eccentricity have always been linked.
